puritan sfrAl C'L'AL'ES GRANT MGCI-ELLN OF JONSGNBURG PENNSYLVANIA .narnia-MAKING Miioiiiunny,

To `all 'ill/710171425 may concern:

Be it known tliat', CHARLES GRANT MC- CLELLAE, a citizen ot the United States. re

siding at Johnsonburg, in thecounty of vElk and State of Pennsylvania, have invented certain new and useful Improvements in.

Papei'-ll/lalninigf,Machinery7 ofwliich the :tollo'u'in is a specicat-ion. y

lily invention relates to impr:nementsv in paper object the provision of means for presenting the *aste particles of paperpulp vas they are being run through the drying and nthe line :c

isliing rolls. In explanation ofi-this object it mayr be stated. that it sometimes happens that the paper pulp, While being run through the' rolls.y breaks, the 'tree end of the pulpl dropping down upon the floor beneath the rolls, necessitating the cutting ofi oi' a considerable quantity of the pulp before it can bel again properly started'tlirough the rolls.

further object otv my invention is t0- )rovide means for )reservino' the Waste ar-,

ticles of pulp from thel stripping knives.'

, iriy improvementy consists in lproviding a construction which will catch these other-y wise Wasted particles of the paper pulp and convey them back to the disintetjrating machinery ivlierethey will be Worked, in with the neuT paper pulp and tiius'saved.'

In the event that the paper pulp, in its passage through' these latter rolls,

breaks,l it will, as before stated, be necessary. to .tear off a-'considerable portio 'of the' pulp, Whichin the Ordinary mode vf tion of the machinery,-` goesto Waste; i

9 represents a series of Winding reels; l0 represents'a pair of stripping knives arY ranged adjacent 'Windingreels;l 11 and l2 Winding reels;v alll of these rolls being of any suitable and ordinarv construction mounted-,in bearings upon t eniain frame e strip of* paperpulp' is shown between the rolls and represented by the reference numeral 13,. Y

Located beneath the resp lct'ive series of rolls is a main conduit l-l haring connectedv Vmayrepresenta still additional series citi@ therewith a yseries of auxiliary conduits' l5,

167 17 and 18, the open end of each of [which terminates preferably just beneath and. betiveen the vrespective series 'of rolls' With the exception of the conduit 1S, which is branched7 assliown at i83 and 15b. said Y branches'being located f lirectlifv beneath the strigjiping knives l0. The upper endof each of the 'conduits5 l5, i6 and 17,*is elongated in the directicn of the. longitudinal axis ot'- the rolls, and the conduit is of a Width preferably slightly greater than the Width of-.tlie material passing through the rolls',

so that when the material breaks, it .will be permitted to duit.v f

In practice the conduit 14 will preferably .be locatedbeneath theiioor lf?) which sup` ports the machinery, with the open ends ot y the auxiliary conduits extending through said ioor.

The discharge end of the conduit. 11i leads to lthe preliminary disintegrating devices, represented by 20V in the drawing, which` ma7 be o t'any suitable and Well-known construction'. vThe particlesfof drop directly 'into the conpulp, asthey fallv into the' auxiliary con- 4 duits, will drop into theinain. conduitand. thence down the main conduit to the disin- -tegra-ting devices, the'inclination of the con dint being such that ordinarily gravity ,will l be sutiicient- 4to carry the particles; through the same, although, -if desired, any` 'ivell lknown 4form-of suctionr 'fan'may be einployed to assist thel particles ofpulpintlieir passage through the conduits. fj

In order to obviate anyv clogging 'of the Waste particles of pulp in thcvconduits, l

disintegrat-ing rolls 21 and 22, each pro- 'vided with a series of teeth-Q3.' coi'iperating Wit-h each other to disintegrate the Waste particles. The rolls are driven froml argv i suitable sourcefof power applied to the piil-= arrange in each ofA the auxiliary conduits prcferaply just beneathl the floor. a pair of,

le f 2d connected `to the roll 2.1; the roll 22v being driven from the roll 2l through the medium of the gears 25 and- 2G. i The gear is smaller than the one 25, so that the roli 22 Will be driven at greater speed than the i'oll-21,for the purpose ofnot only perforniing the disintegrating operation, but

' the disintegrating .also to prevent the paper particles from 'Winding around the rolls.

Before the Waste particles of pulp roach `devices 20, they pass through a second shredder loca-ted in the lower part of the conduit 1 4, this shredder consisting of a revolving roll 27, having 'teeth 28 Which'coperate with teeth 29 pro-- .jecting from a block 30, secured to the Wall of the conduit. The shredded particles tlien pass onto a screen 31, located in -a trough 32 at the lower end of the conduit, Where particles of dirt and other, foreign matter adhering' to the pulp may be re moved, -a' fan 33 of any suitable construc- "tion being employed to dislodge particles of the pulp from the Vbottom of the screen. And having thus 'described my invention,

. l claim:

. In a paper. making machine, the com- .bijnatiom with the rolls for operating upon lthe paper pulp, of a main conduit, a pluthe Alongitudinal axis of.

the paper pulp, of a rality of open.ended auxiliary conduits coinn ,municating 'with said main conduit -and having their open ends located beneath said rolls, the open .ends of said'auxliary conduits being extended in the direction of the longitudinal axis. of saidrolls 4. In a paper making machine, the coinbination, With the rolls for operating upon the paper pulp, and ,stripping knives for said ulp, a main conduit, a plurality of auxiliary conduits communicating said main conduit and extended to a with y point beneath saidv rolls, and. auxiliary conduits also cbininunicating with' said main conduit and extended to points beneath said stripping knives.

5.,`In a paper making machine, the combination, -With therolls :tor-operating upon the paper pulp, of a main conduit, a plurality of open-ended auxiliary conduits communicatingvvith said main conduit and extended to a point beneath said rolls, each ot' said auxiliary conduits having a disintegrating device located' therein.

6. ln a paper making machine, the combination ofthe rolls. and the stripping knives, and a conduithaving .branches ex tending to a point beneath said rolls and lcnives, saidconduit leading to disintegrat-- ing machinery, substantially as andor the pur-pose specified. v D
